Drug administration by effective nano-carriers is an emerging and growing technology in the field of biomedicine and particularly Age related macular degeneration (AMD). This developed nanomaterials based methods with drug administration maximizes the biocompatibility and systemically increases drug delivery profile for the drugs. Herein, we described the effective drug molecules delivery profiles by the hydrothermally synthesized graphene quantum dots (GQDs) encapsulated with supramolecular beta-cyclodextrin (beta-CD) as a drug delivery system for AMD. The drug release profiles were analysed and plotted by two different types of drugs ((Bevacizumab (Bev) and Ranibizumab (Ran))) and compounds displayed an initial burst delivery percentage of 55.7 +/- 1.6% and 52.2 +/- 2.6, respectively, within 15 min. After 1 h, 94.2% (Ran) and 93.1% (Bev) of loaded drug molecules were released from the beta-CD encapsulated GQDs in sustained manner. The biocompatibility of the synthesized carriers was investigated quantitatively and qualitatively with the mouse Fibroblast L929 cell line. The biological cell analysis observed by calculated cell count and green fluorescence visualization has been clearly confirmed the samples are non-toxic and highly compatible to the cells with more than 90% cell viability after 5 days cell culture. The observed material properties and biological results demonstrated that the suitability of the developed nano-carriers for the drug delivery system in the AMD.
